Abstract

The study of optical properties of various photonic band gap (PBGs) structures, focused on the in-plane propagation of 2D-PCs PBGs which are most applied in micro-fabrication and optical integration. These devices provide many novel and useful properties, such as lossless confinement of light mode, high-Q microcavity, linear waveguiding in low index material, low-loss bending, high efficiency resonant tunneling process to transfer energy between defects etc. The parameter interplay on the band gap formation is discussed first, then light modes in ideal bulk PCs are investigated.as finally, interaction between defects crucial to planar device designs. The comparison between the slab with air holes as with microcolumns confirmed that the surface recombination will be smaller in columns as that in air holes when assuming a constant filling factor of semiconductor. The photonic crystals in a square or hexagonal lattice as air holes on silicon on insulator (SOI) layers obtained bandgap centered on the wavelength of 1.55 μm, the spectral region for optical communications. By applications of computational methods like Finite Difference Time Domain (FDTD) could be determined the bandgap of the structure and computed transmission and reflection properties of system.
